3 WELCOME TO THE WONDERFUL WORLD OF AIRBORNE ULTRASOUND INSPECTION Congratulations, you are about to experience the ultimate in airborne/structure borne ultrasonic inspection. Your Ultraprobe 9000 is equipped with features that will help you inspect in the most challenging environment.
4 A. PLUG-IN MODULES TRISONIC TM SCANNING MODULE: This module is utilized to receive air -b orne ultrasound such as the ultrasounds emitted by pressure/vacuum leaks and electrical discharges.
5 TRIGGER ON/OFF TRIGGER SWITCH : The Ultraprobe is always "off' until the trigger switch is pressed. To operate, press the trigger. To turn the instrument off, release the trigger. I/O PORT : This is the RS232 port for upload/download information transfer, including heterodyned sound output.
6 3. ACCESSORIES A. STANDARD ACCESSORIES HEADSET : This heavy-duty headset is designed to block out intense sounds often found in industrial environments so that the user may easily hear the sounds received by the ULTRAPROBE. In fact, the standard headphones provide over 23 dB of noise attenuation.
7 UFMTG-1991: The UFMTG 1991 is a multi directional warble tone generator. It has a high power output with a circular transmission pattern of 360 ° . WTG -2SP WARBLE PIPE THREADED TONE GENERATOR : A .
8 4. OPERATION MODE DISPLAY PANEL : When the trigger is pressed to turn the instrument on, the Display Panel will display intensity levels simultaneously on a bar graph and as a numerical decibel value. The current selected frequency will also be shown.
9 TO ADJUST THE FREQUENCY : • Look at the meter. The kHz indicator must blink to be able to tune the frequency. • If it is not blinking, “Click” in the Sensitivity control dial one time and the kHz indicator in the display panel will blink.
10 TEXT EDITOR: TO ENTER TEXT IN THE TEXT FIELD: • If enabled (refer to SET UP MODE 07), Click the Store Button once after storing data • The text field will blink. If the field has no entry, it will display “UNKNOWN” and the first character will blink.
11 02 Set Time and Date 1. Make sure the Ultraprobe is off. 2. Press (click) both the Yellow Store button and the Sensitivity dial at the same time, then squeeze and hold the trigger.
12 04 dB Offset This position is selected to set the dB scale for readings to be taken in dB offset scale. In order to use the dB offset scale, refer to III above.
13 06 Calibration Due Date Shown as Cal Due Date in the menu, this date is set at the factory and displays the recommended Recalibration/service date. This is one mode that cannot be changed by a user. It is only set at the factory after a service has been performed.
14 09 Exit to program Click the Sensitivity Control dial and you will exit to Operations Mode. 6. USERS INSTRUCTIONS TRISONIC - SCANNING MODULE : • Plug in to front end. • Align the pins located at the rear of the module with the four jacks in the front end of the Metered Pistol Housing (MPH) and plug in.
15 WARBLE TONE GENERATOR (UE -WTG -1): • Turn Tone Generator on by selecting either "LOW" for a low amplitude signal (usually recommended for small containers) or "HIGH" for high amplitude. In high, the Warble Tone Generator will cover up to 4,000 cubic feet (121.
16 A. - APPLICATIONS 1. LEAK DETECTION This section will cover airborne leak detection of pressure and vacuum systems. (For information concerned with internal leaks such as in Valves and Steam Traps, refer to the appropriate sections).
17 particular gas it was designed to sense (e.g., helium). The Ultraprobe can sense any type of gas leak since it detects the ultrasound produced by the turbulence of a leak. Because of its versatility, the Ultraprobe may be utilized in a wide variety of leak detection.
18 1. SHIELDING TECHNIQUES Since ultrasound is a high frequency, short wave signal, it can usually be blocked or "shielded". NOTE: When using any method, be sure to follow your plant's or company's safety guidelines. Some common techniques are: a.
19 The test is conducted by placing an ultrasonic transmitter, called TONE GENERATOR, inside (or on one side) of the test item. The warble pulse -signal from the TONE GENERATOR will instantly "flood" th e test item and penetrate any existing leak hole.
20 TRANSFORMERS, SWITCHGEAR AND OTHER ELECTRICAL APPARATUS E. ELECTRIC ARC, CORONA, TRACKING DETECTION There are three basic electrical problems that are detected with the Ultraprobe 9000: Arcing: An arc occurs when electricity is conducted to “ground”.
21 inspect electrical apparatus at a distance. The UWC 2000 is extremely directional and will locate the exact site of an electrical discharge. Another accessory is the LRM-9- Long Range Module which also increases the detection distance of the Ultraprobe.
22 DETECTING BEARING FAILURE There are two basic procedures of testing for bearing problems: COMPARATIVE AND HISTORICAL. The comparative method involves testing two or more similar bearings and "comparing" potential differences. Historical testing requires monitoring a specific bearing over a period of time to establish its history.
23 Lack of Lubrication: To avoid lack of lubrication, note the following: 1. As the lubricant film reduces, the sound le vel will increase. A rise of about 8 dB over baseline accompanied by a uniform rushing sound will indicate lack of lubrication. 2.
24 3. GENERAL MECHANICAL TROUBLE SHOOTING As operating equipment begins to fail due to component wear, breakage or misalignment, ultrasonic shifts occur. The accompanying sound pattern changes can save time and guesswork in diagnosing problems if they are adequately monitored.
25 4. LOCATING FAULTY STEAM TRAPS An ultrasonic test of steam traps is a positive test. The main advantage to ultrasonic testing is that it isolates the area being tested by eliminating confusing background noises.
26 INVERTED BUCKET TRAPS normally fail in the open position because the trap loses its prime. This condition means a complete blow -through, not a partial loss.
27 5. LOCATING FAULTY VALVES: Utilizing the contact (stethoscope) module in the Ultraprobe, valves can easily be monitored to determine if a valve is operating properly. As a liquid or gas flows through a pipe, there is little or no turbulence generated except at bends or obstacles.
28 ABCD METHOD The ABCD method is recommended to check for the potential of competing ultrasounds downstream that may carry back to the area of inspection and give a false indication of a valve leak. For the ABCD method, 1. Refer to steps 1-5 above. 2.
29 To locate the leak area, gradually position the rod until the leak sound is heard at its loudest point. An alternative to this is to use a flat metal disc or coin and drop it on the test area.
30 ULTRASOUND TECHNOLOGY The technology of ultrasound is concerned with sound waves that occur above human perception. The average threshold of human perception is 16,500 Hertz. Al though the highest sounds some humans are capable of hearing is 21,000 Hertz , ultrasound technology is usually concerned with frequencies from 20,000 Hertz and up.
31 INSTRUCTIONS FOR SETTING COMBINATION ON CARRYING CASE The combination is factory set at ,0 -0 -0,, Setting your personal combination: 1. Open the case. Looking at the back of the lock inside the case you will see a change lever. Move this change lever to the middle of the lock so that it hooks behind the change notch (picture 1 ).
